C:For 2 and 3 Assume you have the following main function and Q2 & Q3 are inserted where indicated:
Please answer how you came to your conclusion!

For 2 and 3 Assume you have the following main function and Q2&Q3; are inserted where indicated: #inciude struct Item char Name [256] int Q int main (int argc, char* argv) OUESTION CODE HERE >> 2) What does the following print to STDOUT? struct Item Joe [5] Joe->Name [0]-A'; * (Joe+1) "Name [O] = Joe->N print f ( " % c" , Joe [1].Name [0]); ame [0] + 1; 3) What does the following print to STDOUT? struct Item *Bob = (struct Jack [1]·Q = 3; printf ("%d", Jack [1] . Q) ; Item* ) malloc (1024);

Explanation / Answer

Q2) The given code snippet would print B to STDOUT.

Explanation: struct Item Joe[5]; this statement creates an array of Struct Item with 5 elements. The name of the array is Joe.

Now, Joe->Name[0]= 'A'; this statement assigns character ‘A’ to 0th array element’s of struct array Joe’s 1st character of character array Name[0].

Next, (*(Joe+1)).Name[0]=Joe->Name[0]+1; this statement assigns next character of Joe->Name[0] to 1st array element’s of struct array Joe’s 1st character of character array Name[0]. Now Joe->Name[0] contains ‘A’ ,so ‘A’+1 adds 1 with the ASCII value of ‘A’ and it would generate ‘B; hence assigning value would be ‘B’.

Now, *(Joe+1) is equal to Joe[1]; hence printf("%c",Joe[1].Name[0]); this statement would print B to STDOUT.

/*NOTE: I think the code snippet of Q3 is not given properly; As Jack is not declared within the code this code snippet would not even compile; I have changed variable Bob to Jack and given the possible output*/

Q3) The given code snippet would print 3 to STDOUT.

Explanation: struct Item *Jack = (struct Item *)malloc(1024); this statement creates a 1024 Bytes of consecutive memory space for approx. 4 Struct Item elements, which is pointed by Jack.

Now Jack[1].Q = 3; this statement assigns 3 to the int variable q of 1st struct array element( assuming index starting from 0). Hence printf("%d",Jack[1].Q); this statement would print 3 to STDOUT.
